Cold Email That Actually Lands.
And Actually Gets Replies.
Most cold email fails before the prospect even opens it. The problem is not your offer; it is your infrastructure. DeliMail fixes the foundation: multi-inbox setup, domain warm-up, SPF/DKIM/DMARC, AI personalisation, and deliverability monitoring, all managed for you.

Why Most Cold Email Fails Before It Even Starts
The number one reason cold email does not work is not bad copy. It is infrastructure. Emails that land in spam never get read, no matter how good they are.
Reality check
In Saleshandy’s analysis of 53.1 million cold emails, fully authenticated domains were 2.7 times more likely to land in the inbox than unauthenticated ones.
Sending from your main domain
Why it kills your campaign: One spam complaint can blacklist your primary business email, the same one your clients and prospects use to reach you. Never send cold outreach from your main domain.
DeliMail fix: DeliMail uses dedicated sending domains, separate from your main email, which absorb all campaign risk.
No domain warm-up
Why it kills your campaign: A brand new email domain sending hundreds of emails per day looks exactly like spam to Google and Microsoft. Their filters will route you to junk before your first prospect even sees the subject line.
DeliMail fix: DeliMail warms every new domain for four to six weeks before campaign volume starts, building sender reputation gradually.
Missing SPF, DKIM & DMARC
Why it kills your campaign: These three DNS records tell email providers that you are authorised to send from your domain. Without them, your emails fail authentication checks and land in spam, or get rejected entirely.
DeliMail fix: DeliMail configures SPF, DKIM, and DMARC on every sending domain as part of setup. No technical knowledge required.
Sending too much from one inbox
Why it kills your campaign: Google Workspace allows up to 2,000 messages per user per day, but that is a platform ceiling, not a safe target for cold email. Senders who push thousands of emails through a single address build a poor reputation quickly and wonder why nothing lands.
DeliMail fix: DeliMail spreads send volume across multiple inboxes on multiple domains and ramps slowly, keeping every mailbox far below the platform ceiling.
Running Several Campaigns at Once
Teams that run outreach for several offers, regions or clients face a unique challenge: each campaign targets a different audience with different messaging. A single self-serve tool like Smartlead or Instantly can handle this technically, but the operational overhead of managing multiple campaigns, multiple domain sets, and multiple warm-up schedules is enormous. DeliMail as a managed cold email service handles all of this operationally, giving you the outreach without the operational load.
Cold Email for Referral-Led Businesses
Established businesses and professional-services firms are rarely natural cold emailers. You built your business on referrals and relationships, and that is fine. But referrals dry up, and the feast-and-famine cycle is real. Cold email outreach, done correctly with the right infrastructure and targeting, gives you a steady pipeline channel that works in parallel with referrals, without you becoming a full-time marketer to maintain it. See how it works for your industry.
The Infrastructure Behind Every Campaign
DeliMail is not just a sending tool. It is a complete managed cold email infrastructure, built so your campaigns land in inboxes and generate replies.
Multi-Inbox, Multi-Domain Architecture
DeliMail sets up multiple sending domains and multiple inboxes per domain, spreading your send volume so no single address or domain ever carries too much load. This is one of the most important factors in cold email deliverability, and it is completely handled for you.
Domain Warm-Up
Every new sending domain goes through a four to six week automated warm-up process, gradually increasing send volume to build a positive sender reputation before campaigns begin.
Skipping warm-up is a common cause of cold email landing in spam. DeliMail never skips it.
Emails That Feel Written for That Prospect
DeliMail's AI writes custom opening lines for each contact, referencing their company, role, and recent activity. Not mail merge. Genuine personalisation at scale.
Smart Follow-Up Sequences
A single email is rarely enough. DeliMail automates personalised follow-up sequences that adjust based on whether the prospect has replied. Persistence without being annoying.
Deliverability Dashboard & A/B Testing
Track reply rates, bounce rates, meetings booked, and inbox placement across every campaign. Open rates are unreliable because Apple Mail Privacy Protection inflates them, so we optimise for replies. Run A/B tests on subject lines, opening lines, and CTAs, all visible in one dashboard.
Inbox Placement: Authenticated vs Unauthenticated

DeliMail vs Smartlead vs Instantly
Smartlead and Instantly are excellent self-serve tools, if you have the time, knowledge, and operational capacity to run them. DeliMail is the managed alternative for businesses that want the results without the overhead.
The key difference
Same Infrastructure. Zero Operational Overhead.
Smartlead and Instantly use the same underlying email infrastructure principles as DeliMail. The difference is not the technology, it is who operates it. DeliMail is a done-for-you cold email service. You get the same kind of infrastructure, without the setup, warm-up, copywriting, monitoring and reply handling landing on you.
Who Is DeliMail Built For?
DeliMail is built for established B2B businesses and professional-services firms across industries that need a steady pipeline channel, without becoming cold email experts to get one.
Your Outreach. Fully Managed.
You focus on closing meetings. We handle everything else, infrastructure, copy, warm-up, sequences, and deliverability.
Teams Running Several Campaigns
Run managed cold email campaigns for several offers or clients simultaneously, each with their own domain infrastructure, sequences, and targeting. DeliMail scales across your portfolio without multiplying your operational workload. The managed service model means your team stays focused on strategy, not inbox management.
Referral-Led Businesses
Your business grew on referrals. DeliMail adds a second engine running in the background, targeting decision-makers in your ideal client profile, warming them up over a sequence of personalised emails, and booking calls directly into your diary. You see the meeting. We handled everything before it.
Relationship-Led Sales
High-value services are a relationship business, but relationships need a starting point. DeliMail creates those starting points at scale, reaching CFOs, CEOs, and department heads with messages that feel like they were written by a peer, not blasted by a marketing tool.
Signal-Led Outreach
DeliMail is one of the channels that acts on signals: first-party signals from DeliChat, and trigger signals such as role changes, funding rounds and hiring found in research. Opens, clicks and replies feed the same score. See signal-based outbound.
Volume That Grows With Your Reputation
DeliMail is $199 a month. Sending volume is set by what your domains can safely carry, not by a plan.
Spread the load
Send volume is split across multiple sending domains and multiple inboxes, so no single address or domain carries too much.
Ramp slowly
New mailboxes start at roughly 5 to 10 emails a day in weeks one and two and reach 20 to 30 a day in weeks three and four.
Stay far below the ceiling
Google Workspace allows up to 2,000 messages per user per day. Cold senders keep each mailbox well below that and let volume grow with reputation.
How a DeliMail Campaign Goes Live
ICP & Targeting
We work with you to define your ideal client profile, industry, company size, geography, job title, and buying signals. This is the foundation everything else is built on.
Domain Setup & Warm-Up
New sending domains are purchased, configured with SPF/DKIM/DMARC, and put through a four to six week automated warm-up process. This runs in parallel with copy development.
Copy & Sequence Development
Our team writes your outreach sequence, opening email plus 2–3 follow-ups, with AI-personalised opening lines for each prospect. All copy is reviewed and approved by you before launch.
Campaign Launch
Once domains are warmed and copy is approved, campaigns reach full volume. Send volume ramps gradually to maintain deliverability, and first meetings typically arrive in weeks four to six.
Optimisation & Reporting
Weekly performance reporting on reply rates, bounces, and meetings booked. A/B tests run continuously. Sequences are refined based on what is working. Deliverability is monitored daily.
Simple, Published Pricing
DeliMail is $199 a month on its own, or $499 a month together with DeliChat and DeliReach. Managed Outbound is $2,500 a month on monthly billing, or less with quarterly and annual billing. Full detail is on our pricing page.
DeliMail covers domain setup, warm-up, campaign management, copy development, deliverability monitoring, and weekly reporting. No long-term contracts on monthly billing.
Email is one channel in our managed Outbound package, which is the same service as our outsourced SDR. See B2B lead generation services for how signal-based outbound works.
